Double cluster in Perseus

Object name: Double cluster in Perseus NGC 869 and NGC 884
Object type: Open cluster
Location: Bogotá, Colombia.
Date: 06-NOV-2012
Media: Graphite pencil and yellow notebook paper. Scanned and inverted.
Equipment: 15X70 Binoculars

Hello all,

Since June of the last year i started this hobbie to sketch the objects i saw from my very light polluted area. As a begginer i think is a good way to learn and memorize the sky. This page and also ronys site are my favorites and i would like to make a page like that. Unfortunately i still have some problems trying to make better my sketches by using photoshop.

This sketch was performed on 3 nights of observation and it was easy to find from deltha Cas because my view of Perseus is obstructed by my neighbor building. In the denses areas of the cluster i can not resolve the stars but they together are seen like an clearer area compared with the reddish/blue (becasue LP) background.

Thanks to all for watching.

Bodes Nebulae: M81 and M82

Object: M81\M82 Galaxies in Ursa Major
Scope: 10″ Newtonian
Eyepiece: 36mm Baader Hyperion, FoV 2,07°
Date of scetch: 12.29.2012
Location: Kalteck, Bavaria, Germany

Just before the New year me and my buddy packed our gear and went on a small mountain where we occasionally enjoy the Nightsky . Though my friend is more into photographic Astronomy we sometimes try our skills at the same Objects and share our Scetches\Photos what’s great to compare. Especially if someone asks you if you can see all the colors and details through your scope that they know from Hubble images in Media.
It was a pretty good night with excellent seeing and good transparency. Only 95% illuminated Moon was a little annoying then. Bodes Nebulae are always a nice view.
Made a few scetches that night. This is my first one to post here. There’ll probably be more.

Markarian’s Chain

Markarian’s Chain superb spring object, this curved line of galaxies is my favorite part of the Virgo Cluster. I sketched 10 of them visible in the 16-inch telescope in small-town suburbia (naked eye limiting magnitude is about 5)

I noticed exactly 10 galaxies from the left:

Ngc 4477
Ngc 4473
Ngc 4458
Ngc 4461
Ngc 4435
Ngc 4438
Ngc 4402
M86
M84
Mgc 4388

Of course, the sketch doesn’t represent the field of view 72 degrees (22mm, eyepiece)- it was just sketched by moving the tube 😉 Power is almost about 82x

Yours Robert

McNeil’s Nebula

Friends:

Here is my submission, which is, I think, not only my best sketch to date, but also my most valuable one: as I cannot find any other one of the nebula during its short 2008 outburst.

* Object Name (McNeil’s Nebula)
* Object Type (Likely emission nebulosity, outburst of V1647 Ori)
* Location (Santa Cruz mountains, north of Santa Cruz, California)
* Date (12-20-08)
* Media (graphite pencil, white black paper)

The sketch was made in my logbook after a long study about the the nebula, careful preparation of regional charts, and intense scrutiny during a session arranged just for this observation, using my Orion XT-10 Sky Quest 10 inch Dobsonian (f/4.7, 5 mm Orion Stratus eyepiece [240x, 1.1 mm exit pupil, ~17′ FOV], without filtration.)

Sue French, “Deep Sky Wonders” columnist for “Sky & Telescope” magazine, had carefully observed the previous outburst of McNeil’s nebula in 2004, with a 10″ Newtonian (confirmed by Joe Bergeron.) She studied my report and first and second drawings, and commented in reply, “You no doubt saw McNeil’s reflection nebula.”

My lengthy article about the nebula, and this observation, is found at:
http://freescruz.com/~4cygni/astro-app/essays/fuzzy-objects09.htm#McNeil

This article discusses the meteorological conditions, and many other aspects of my quest to see it, and the actual experience, plus my background research. The viewing location was a rural private road in the Santa Cruz mountains, south of San Jose and north of Santa Cruz, at an elevation of 3,400 feet (site of some previous Don Machholz comet discoveries.) The drawing shown was confirmed by me with a second sighting and sketch made with a C-11 telescope, at Lake San Antonio further south, on 12-28-08.

Frosty Leo

Object name: Frosty Leo (IRAS 09371+1212)
Object type: protoplanetary nebula
Location: Nádasdladány, Hungary
Date: 2013.03.07 21:15 UT
Media: B + 5B pencils on white paper, inverted digitally
Telescope: 12″ f/5 Newtonian on Dobsonian mount
Magnification: 469x
Seeing, transparency, SQM: 5/1, 3/5, 21.16 MPSAS
Temperature: 280 K

Description:
A rarely observed protoplanetary nebula I’ve first read about in Cloudy Night’s Sketching forum. It’s as small as expected, but much fainter. Elongated to the N-S, with a clearly visible dark band divinding the nebula to to halves, when the seeing gets better for a few moments. Reminds me of a faint little nearly edge-on galaxy. I haven’t checked photos of this object before my observation, so I’m quite surprised now that I’ve seen the dark band, because even on a sketch made with 600mm scope it does not show up. But I know that my eye did not lie. A highly recommended gem.

The Lonely mountain

Mons Pico and surrounding terrain
Hover cursor over image to view labels.

Object Name: Mons Pico and surrounding terrain.
Object Type: Lunar mountain.
Location: York, UK
Date: 19th April 2013
Media: graphite pencil on white paper

A Day 9 moon and clear skies, and Friday, all meant sketching. Mons Pico is an isolated mountain peak (2400m) in the north of Mare Imbrium. The mountain probably marks the northern border of the inner basin ring of the Imbrium, which was afterwards mostly flooded by Mare lavas. For context I also filled in some of the surrounding peaks and nearby Plato. Wrinkle ridges on the Mare near to Pico form a roughly circular outline with the Mountain border to the north, suggesting that they mark the rim of a buried crater, known as Ancient Newton. However, there is still no confirmatory evidence of this. Pico is about 10km long. Montes Teneriffe, to the West, are about 100km long tip to tip.

NGC 6337

Object Name: NGC 6337.
Object Type: Planetary Nebula. Apparent mag. ~12.3.
Location: San Miguel, Buenos Aires Argentina.
Date: 23/04/2013 2:00 AM.
Media: Digital tools. PS 5.

Located in a rich star field in Scorpius, i tried to see the central asterism of the nebula but i couldn’t (only the brightest star). Link of the asterism here: http://www.capella-observatory.com/images/PNs/NGC6337.jpg. I’ll try again in rural skies.

Telescope: Dobson 12″ F/5.

Eyepiece: SP 6.3-10 mm.

Filter: Televue Bandmate Nebustar UHC. (Sometimes).

Bortle Dark-Sky Scale: 8-7, Urban/Suburban Sky.

Thank you and best regards.

Full Disc H-Alpha – April 22, 2013

H-Alpha Sun - April 22, 2013 — H-Alpha Sun – April 22, 2013

Object Name: Sun
Object Type: Star
Location: Deventer, The Netherlands
Date: April 22, 2013
Media: White pastel pencil on black paper, colorized and mirror reversed with Photoshop

Sunny weather + long lunch break = solar observing!
This afternoon I took 30 minutes to sketch the Sun in h-alpha. It’s been so long since my last solar sketch, I even had to search for the pastels. I made a full disk sketch, the active region AR1726 was large enough so see in detail even at low magnifications. For this sketch I used a 22mm LVW (32x) in my 70mm h-alpha telescope.

Kind regards,

PanSTARRS and the Andromeda Galaxy

I made this sketch using my 15×70 binoculars at 1:45 UTC on 4/5/2013. I was just able to get both objects in the the field of view. The comet was brighter than M31, particularly in the core, but smaller. The comet’s tail was noticeably wider than it was when I observed it a few weeks earlier on 3/13. It was an interesting conjunction but was hard to get a lot of detail, M32 and M110 were not even visible, because they were both about 10-15 degrees from the horizon.
